3600 Muffler / Exhaust Options

[LarryBud]

I use a 3600 for Brush Hog / mowing work. I'll be converting 18 acres from pollinator habitat to pasture the next few years which will require frequent mowing( many hours of seat time ). Current set up is an upright muffler running up outside the hood which 90 degrees out approx 6" above my seated head. With any wind at all I'm eating more fumes than I'd like on half the runs. I also store it in a shed with a door which will not all me to add too much more height.

Would it make sense to cut off the 90 and then use a slip on extension? I'd need to remember to pull it off every time I store it ( which will probably lead to a mishap ). Or, do I go horizontal which would require a new manifold and a lot more work. I do need to mow in some tall grass weeds from time to time.

Suggestions?

Your tractor has the manifold for horizontal exhaust that someone has installed a modified vertical exhaust on
Factory vertical exhaust goes up through the hood panel
First thing I’d try is cutting off the elbow and letting the exhaust blow straight up, blowing out sideways keeps it at that level were the wind can blow it back at you. If you keep it stored inside most times I wouldn’t worry about a rain flapper

My 2600,diesel goes up through the hood and fumes are not a factor, I've even shortened the pipe because it caught low branches. on the other hand my gas tractor had a vertical exhaust and it was not good so I put a horizontal exhaust on it and don't have any problems unless I leave it running to hook up.

Or get/make the parts for the horizontal exhaust, and run it under the left step plate.

Like Destroyed said, you already have the manifold for a horizontal exhaust. I'd go that route for your purposes . It would also make it effectively quieter, as the outlet would be farther from your ears. The factory vertical exhaust would be at least 18" farther forward. Doesn't seem like much, but it's noticable from the operator's seat.

Thanks for the replies. I'll do some homework and make a decision.

The extension is the right answer.....I have the 3600 with the horizontal system and it is noisy and has the potential to start a grass fire. I converted a 2000 from horizontal to vertical and it wasn't that hard. On the long outlet in the enclosed photo, install the long extension after you cut the curved end/tip off and install an exhaust pressure operated flapper valve....solves your problems.

The way his exhaust curves up into the manifold a exhaust flapper isn’t necessary
I’d cut the elbow off and try in like that, if it still allows exhaust to get in his face then add a extension only long enough that it would still allow the tractor to fit throw the door of his shed

I do see the curve into the head but sitting out in any kind of storm, I'd be skeptical on the curve filling with water but none gets into an exhaust valve and subsequently cause problems especially on a Diesel. I have 84 and 65 HP tractors with curved exhaust and I don't like them...but I keep my tractors under sheds or shed tops and I don't worry about it. If your rain gauge with usually a smaller opening, if rainwater/snow couldn't get into a small hole, how do rain gauges work? I have a flapper on the straight exhaust I put on my ford, through the hood over the engine as you said. I forget their name but I think its #5 of their series is for fords and is really quiet. When I installed my flapper, I installed the flapper plate in the operator/s direction which helps to deflect some of the engine exhaust noise and helps to keep the exhaust out of the operator's station.

I agree that somebody put an aftermarket exhaust manifold on that tractor......that muffler looks like a glass packed auto muffler of the 50-80's noise makers on autos.....I was one of those.....

It’s probably not a aftermarket manifold, it’s just the manifold style for horizontal exhaust. Since there’s no hole in the hood for a factory vertical exhaust I’d say the tractor came with horizontal exhaust and someone made up that vertical setup

Pretty sure this is the case. The mod is well done except for the fume factor. I'm going to cut off the 90 and ad an extension that will fit in my shed door as option 1. If I still have issues, I'll look at going horizontal.

When I went to vertical on a 3910, I forget where I found it, but I found a used vertical hood section (factory vertical hole) somewhere so that I didn't have to cobble a hole in the existing rear exhaust system. Did have to change the manifold on that tractor but I think earlier models of the 3000 series could flip the manifold up or down to accommodate either outlet direction.

 

[Destroked 450]

No the manifolds are different, horizontal manifold has a nipple the pipe slides over and held with a clamp, vertical manifold is extended with a hole for the pipe to slide inside and no way the clamp it
Also if you flip the vertical manifold the pipe would hit the oil filter, flipped horizontal manifold would move the pipe forward of the hole in the hood

Thinking if it blew forward you would not smell it. For sure if you can go straight up it will get away. Worst case if the system vibrates or shakes you could secure a simple brace from the hood to the upper pipe. A piece of 1/8 x 1 1/4 flat would secure it. Secure it to hood with a nice size self tapping screw. Then use a muffler clamp to secure to upper pipe.
